The Island

The first floor is comprised of a central open chamber with a dias to the east and smaller side chambers to the north and south. The stairs down go under the raise dias and there is room for two attackers, long weapons, like edishams Shillelaugh or ranged attacks, would be better suited but you can crouch down to swipe at them as they come up the stairs. There is noting loose to shift over and drop. The casket lids can be moved but are very heavy and it would take all of you to move one.

Elph moves up to block the stairs with Eddisham and Baruman takes a couple of steps down so he can swing more easily as skeletons begin pouring up and out of the stairs into the room

The skeleton crumbles and another moves to replace it. Though the swamring mass of undead appears endless as they poor from teh stairs the sounds of feet comingup the staris indicate there should be an end.
Eventually.

Baruman scrambled to recover swinging wildly to keep the undead at bay and manages to knock it's head clear off!

Shmautz stabs a skeleton and it bursts into dust and another steps up to take its place
Elph knocks one down at his feet but another moves into take its pace.
